White Label Armory Gas Key Features The White Label Armory Gas Key is a precision steel component that channels high pressure gas from the barrel back into the bolt carrier powering the cycling of the action on both AR10 and AR15 platform rifles. A gas key that is not properly finished or staked can loosen or leak gas over time leading to short stroking failures to cycle or inconsistent function. This gas key is machined from steel and finished with a nitride treatment giving it greater surface hardness and corrosion resistance than a standard phosphate finish. That added durability helps the key withstand the repeated heat and pressure cycles it experiences every time the rifle fires. Built to fit both AR10 and AR15 bolt carrier groups the gas key is a versatile replacement part for shooters running either platform. Replacing a worn pitted or poorly staked gas key restores consistent gas flow and reliable cycling without requiring a full bolt carrier group replacement. The black nitride finish gives the part a clean durable appearance that resists corrosion better than an untreated or basic phosphate coated key. For AR10 and AR15 owners performing bolt carrier group maintenance or upgrades the White Label Armory Gas Key is a dependable replacement part available for sale at GrabAGun.
